Abstract

Appareil de mesure de quantité de chaleur cédée par un flui e à un dispositif consommateur, comportant un pont électrique de mesure (R1 , RV R'1 RR ) de la différence de température produite par le consommateur, un appareil de mesure de consommateur, un oscillateur 10 délivrant, à chacune de ces impulsions, une suite d'impulsions, lesquelles sont additionnées par un compteur 8. Un convertisseur analogique/numérique à double rampe 7, 12 reçoit la tension de mesure de température U, et une tension de référence UR proportionnelle à celle qui alimente le pont de mesure, ainsi que les impulsions de l'appareil de mesure de volume A qui commandent son cycle. Un second compteur 9, lorsque la tension de mesure est appliquée au convertisseur, compte les impulsions de l'oscillateur et, au bout d'un nombre donné d'impulsions, applique la tension de référence au convertisseur et les impulsions de l'oscillateur au premier compteur 8. Application : mesure de quantité de chaleur.
